In order to collect more convincing data on the aetiological agent of young pigeon disease syndrome (YPDS), a comprehensive study was performed pigeons in German lofts with or without outbreaks YPDS. The investigations included examination histories, clinical signs and pathology, as well parasitological microbiological analysis. Pigeons their 4th 12th week life exhibited at higher frequency greater severity than other ages. Greenish liquid crop, proventriculus ventriculus, yellow fluid small...
In humans, the clinical and molecular characterization of sporadic syndromes is often hindered by small number patients difficulty in developing animal models for severe dominant conditions. Here we show that availability large data sets whole-genome sequences, high-density SNP chip genotypes extensive recording phenotype offers an unprecedented opportunity to quickly dissect genetic architecture conditions livestock. We report on identification seven de novo mutations CHD7, COL1A1, COL2A1,...
Schistosoma reflexum (SR) is a lethal congenital syndrome characterized by U-shaped dorsal retroflexion of the spine and exposure abdominal viscera. SR usually associated with severe dystocia. The thought to be inherited as Mendelian trait. We collected series 23 SR-affected calves from four breeds (20 Holstein, one Red Danish, Limousin, Romagnola) performed whole-genome sequencing (WGS). WGS was on 51 cattle, including 14 cases parents (trio-based; Group 1) nine single (solo-based; 2)....
Summary Objective of this study was the improvement selected parameters udder health by mastitis vaccination in a dairy herd with elevated bulk milk somatic cell counts and Staphylococcus (S.) aureus as predominant causing pathogen. Material methods: On farm, pregnant heifers (status group [SG] 1; n = 181) well cows stratified for their state (classification based on results cytobacteriological investigations quarter samples obtained before dry cow therapy [MS0]) (SG 2–4; 416) were randomly...
Coxiella burnetii (C. burnetii) is the causative agent of Q fever both in humans and animals. The objectives this study were to investigate seropositivity bacterial shedding heifers primiparous cows an endemically infected herd assess effects on post-partum diseases, fertility milk production. At age 9 months, 96 Holstein included. Sampling was performed reproduction-orientated: at beginning study, detection first pregnancy, 3 weeks before expected calving date (blood serum), parturition...
Abstract Background Hippoboscid flies are bloodsucking arthropods that can transmit pathogenic microorganisms and therefore potential vectors for pathogens such as Bartonella spp. These Gram‐negative bacteria cause mild‐to‐severe clinical signs in humans animals; therefore, monitoring prevalence louse fly populations appears to be a useful prerequisite zoonotic risk assessment. Methods Using convenience sampling, we collected 103 adult from four ked species ( Lipoptena cervi , n = 22;...
The current prevalence of avian leukosis virus (ALV) in fancy chickens Germany is unknown. Therefore, 537 cloacal swabs from 50 purebred fancy-chicken flocks Saxony were tested for the presence ALV p27 protein using a commercial antigen-capture ELISA. detection rate was 28.7% at individual-animal level and 56.0% flock level. Phylogenetic analysis PCR products obtained 22 different revealed highest similarity to subtype K. When classifying breeds by their origin, rates differed significantly....
Indigenous poultry breeds represent an important animal genetic resource. However, their characteristics in respect of performance, product quality, and integument condition are often poorly investigated. Therefore, the local Saxonian Chickens (SaChi) German Langshan bantam chickens (GLB) different plumage colours were characterised. The high-performing hybrid strain Lohmann brown (LB) served as control group. For each group, 60 hens 6 roosters studied extensive free-range system from 21–80...
Severe feather pecking is a damaging allopecking behavior in pullets and laying hens which was found to be associated with multiple factors. The aim of this study investigate whether the occurrence could reduced by additional environmental enrichment materials (EM; stones hard-pressed alfalfa bales) littered housing system. In total 4,000 (2000 Lohmann Brown classic [LB] 2000 Selected Leghorn [LSL]) were reared an aviary system until week 18, 1,320 remaining kept thereafter, from 19 48....
The aim of this study was to investigate the effect additional enrichment materials (EMs; pecking stones and alfalfa bales) on occurrence plumage damage, skin injuries, toe with an emphasis possible differences between commercial hybrid strains laying hens. During rearing (weeks 1–18, 16 compartments, 4000 pullets) periods 21–72, 24 2808 hens) in a littered housing system, EMs were permanently provided groups (EXP), while control (CON) did not receive EM. In two-factorial design (two four...
Aristaless-like homeobox 4 (ALX4) gene is an important transcription regulator in skull and limb development. In humans mice ALX4 mutations or loss of function result a number skeletal organ malformations, including polydactyly, tibial hemimelia, omphalocele, biparietal foramina, impaired mammary epithelial morphogenesis, alopecia, coronal craniosynostosis, hypertelorism, depressed nasal bridge ridge, bifid tip, hypogonadism, body agenesis. Here we show that complex malformation the hind...
Abstract A total of 289 cloacal swabs from pigeons 29 different breeders in Germany were collected. In addition, samples exhibited at shows The detailed health status the pigeon flocks was recorded. Samples analysed for presence recently discovered rotavirus and circovirus. Pigeon found 10.3% circoviruses 65.5% sampled lofts. study revealed a strong relationship between attendance occurrence clinical signs. higher prevalence animals indicates that exhibitions are risk factor transmission...
Abstract Background/introduction In the absence of evidence‐based findings for Saxonian Chicken (SaChi) and German Langshan bantam (GLB), which are indigenous endangered fancy chicken breeds, objective present study was to characterise their growth performance meat potential in an extensive free‐range system Methods A total 340 hatching eggs from SaChi 439 GLB were provided by private breeders, 263 (77.3%) 174 (39.6%) hatched ( p < 0.001) Results By week 20, reached body weights 2362.3 ±...
The objective of this study was to evaluate the beneficial effects erythromycin (Emy), a prokinetic drug active at level abomasum, duodenum and proximal duodenum, in dairy cows undergoing laparoscopic repositioning left abomasal displacement (LAD). A total 71 German Holstein were randomly assigned into three groups. Cows group Emy1 received once preoperatively (10 mg/kg; intramuscularly). Animals Emy3 additionally treated twice after surgery intervals 24 h each intramuscularly), while...

Feather pecking and cannibalism are 2 major problems in laying hens' husbandry. Although additional environmental enrichment material (EM) supply is thought to lessen these problems, consistent evidences lacking. This study examined the effects of EM (pecking stones alfalfa bales) on biological performance, carcass composition, animal losses a littered housing system. 2,000 brown-egg white-egg layer hen pullets genetic strains Lohmann Brown classic Selected Leghorn classic, respectively,...
